As at home rolling through ancient narrow alleys in Old World cities as it is through gleaming modern airports, the Patagonia Black Hole 45L Wheeled Duffel does it all. Highly water-resistant thanks to the TPU-film laminate and DWR coating, and super durable because of the 1200D polyester fabric, the Black Hole 45L can take a beating—and keep rolling. $299.
